hi,

see to revise the old lessons it is best to revise it from the text books which you have studied in 11th and 12th class. in short space of time it would be difficult to revise from any new books which you are not familiar before. however based on students review ncert books are best text and it covers the main syllabus which is best for any of the entrance test. apart from studying text book you have to practice mcq from arihant experts or must go through the previous years questions.
